Observations of afterimages indicate that red and green cone sensitivities can be modified jndependentiy by bieaehing. providing a way to estimate their sensitivities in the normal eye. The fovea1 afterimage of a red and green bipartite held is allowed to fade against a steady red background. A change of background color from red to green generally revives a bipartite afterimage. If two conditi...
Neurobiological and molecular studies suggest a dichromatic colour vision in canine species, which appears to be similar to that of human red-green colour blindness. Here, we show that dogs exhibit a behavioural response similar to that of red-green blind human subjects when tested with a modified version of a test commonly used for the diagnosis of human deuteranopia (i.e. the Ishihara's test)...
Muscadine grapes (Vitis rotundifolia) are the most widely planted grapes in the south and southeast United States due to their suitability in these areas. Most of the commercial muscadine grape crop is used to produce wine. Wine made from suitable cultivars of muscadine grapes possesses a very fruity, unique flavor and aroma that appeals to many people in the South. However, muscadine grape pro...
The evolution of trichromatic color vision in primates may improve foraging performance as well as intraspecific communication; however, the context in which color vision initially evolved is unknown. We statistically examined the hypothesis that trichromatic color vision in primates represents a preexisting bias for the evolution of red coloration (pelage and/or skin) through sexual selection....
Melanocortin 1 receptor (MC1R) gene variants are associated with red hair and fair skin color. We assessed the associations of common MC1R genotypes with the risks of 3 types of skin cancer simultaneously in a nested case-control study within the Nurses' Health Study (219 melanoma, 286 squamous cell carcinoma (SCC), and 300 basal cell carcinoma (BCC) cases, and 873 controls). We found that the ...
The arousal theory of color proposes that red is associated with arousal. Research on the color-in-context theory, in turn, states that the context in which red is perceived influences its valence-related meaning and behavioral responses to it. This study faces and integrates these theories by examining the influence of red on both arousal and valence perceptions of test-relevant and neutral st...
In visual search for a conjunction it is much more difficult to search for the conjunction of 2 colors or 2 orientations than for Color x Orientation or Color x Shape conjunctions. The result is not limited to particular colors or shapes. Two colors cannot occupy the same spatial location in Color x Color searches. However, Experiments 6 and 7 show that Color x Shape searches remain efficient e...
Recent research indicates a direct relationship between low-level color features and visual attention under natural conditions. However, the design of these studies allows only correlational observations and no inference about mechanisms. Here we go a step further to examine the nature of the influence of color features on overt attention in an environment in which trichromatic color vision is ...
color is one of important elements in area of feelings that plays an important role in our life and is a symbol for expression of feeling as sadness and happiness. therefore, color is an additional aspect that provides many meaning for a literary man so that he can picture beauties of creation by means of it. it is decodification of secret meanings of the colors by which litreary man's tho...
